Specification of Letters Patent.

Patented Dec. 28, 1909.

Application filed September 18, 1908. Serial H0. 458,592.

To all whom it may concern:

Be it known that I, Louis CAUL, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Agitating Devices for Mixing Carbonic-Acid Gas and Water, of which the followin is a full, clear, and exact description, re erence being bad to the a ccompa uyi n g dra wings.

My invention relates to apparatus for impregnating water with carbonic acid gas and more particularly provides a devlce which is designed to thoroughly agitate the water and gas as they come into contact so as to secure a complete and intimate mixing of the same. Moreover, the device here shown and described secures a uniform mixture of the water and gas.

Generally speaking, the invention comprises the elements and combinations thereof set forth in the claims.

Reference should be had to the accompan ing drawin forming a part of this appicatlonin wnchigure 1 IS a diagrammatic illustration in elevation of a complete apparatus embodyin my invention for impregnating water with carbonic acid gas; Fig. 2 is a sectional elevation of the mixing chamber containing the agitating device and showing the operating mechanism for the agitator; Fig. 3 is a longitudinal section upon the line :v-:n of Fig. 2; Fig. 4 shows a perspective view of the agitator.

In Fig. 1 is shown an assemblage of the various elements comprising the apparatus necessary to charge water with carbonic acid gas. In the drawing 1 designates a hunk designed to hold carbonic arid gas under ressu re. 2 designates a water pump which, 1y means of suitable pipes El and 4, is rounected with a source of water supply. 5 designates the pump operating means.

Leading from the gas tank 1 and from the water pump 2 are pl ms l3 and 7. which are adopted to convey the gas and water rcspcctlvely to a receptacle 3 which 1 designate a mixing chamber. ll" desired, the water impregnated with lhe gas may be drawn du'cctly from this chmulwr and passed into the iron cylinders muployed In store the wulcr charged with "us and to l-rm'mpurt the some. 'lhese tau s are well known in lhe url. However, I. prefer to employ in eouumniou with the mixing receptacle a storage or reservoir tank which is indicated at 9. The mixing receptacle 8 is connected with the tank 9 so that the water after being thoroughly mixed with the gas will pass into the said tank 9 and may be drawn therefrom, so as to till the ordinary iron transportation tanks, through the valve 10. The gage 11 which connnunicates with the interior of the tank at oints near the top and bottom thereof will indicate the helght of the charged water within the tank 9.

The water pump and the engine for operating the pump are in alinement as is customary, and a piston rod 12 operated from the engine 5 extends between the en- 'inc 5 and pump 2 to operate the piston.

he pump and engine-are connected by means of a frame 13 which frame is cylindrical at top and bottom and is securely fastened to ad acent ends of the pump and enine, the top and bottom pieces being joined y vertical ribs 14, as shown in Figs. 2 and 8.

A shaft 15 is jonrnaled in one of the side members 14 and extends on both sides thereof. Upon the inner side is secirred a small 1' 16 which meshes with a rack 17 which is carried by the piston rod 12. This rack may be formed as a part of the piston rod or may be separately formed and secured thereto. Upon the outer end of the shaft 15 is secured a gear 18.

A shaft 19 is journaled at one end in the same frame member as the shaft 15. The said shaft extends throu h the mixing receptacle 8 and is jouruai ed at its opposite end in :1 lug projecting from said casing. The shaft ill carries a gear 20 which is socured thereto and is in mesh with the gear 13. The gems 1S and .20 are removable from the shafts with which the; are n-s mclivcly engaged so lhul gears of dillcrcnl rnlios may be subslitulod upon the shafts.

mixing or agitating device is secured to lhnt purl of the shaft 19 which is comprobended between the walls of the mixin" rc repluole. This mixing device may be oFnny suitable form lo thoroughly ugilulc the walo! and mix the same with the gas which is admitted lo the interior of the mixing receptacle. The device which I have shown comprises four blades .21 mounted at right angles to curb other and secured upon the shaft in any suitable manner. These blades are provided with warlorutious so as to more thoroughly mix the water and gas.

The mixing receptacle 8 is made in two parts, a lower part which is semi-spherical in shape and a cap 8. The cap and lower portion of the receptacle are m screwthreaded engagement so that. they may be separated and access to the Interior 0 the receptacle 8 be readily obtained. Upon the cap are two projectin nipples 22 and 23 which are screw threa ed and engage with couplin members 24 and 25 by means of which t e are 'oined to the pipes 6 and 7 res ective y. T e ni ples 23 are provided wit check valves so t at the water and gas having once entered the chamber within the receptacle 8 may not be forced back through the pipes (5 and 7.

The lower portion of the bottom part of the receptacle 8 is formed in the shape of an outletpipe 26 which is screw threaded at its lower end so that it may engage with a suitable union u n a pipe which may communicate with e ordinary transportation tanks, or, as in the instance shown, the pipe 26 may be connected directly with the reservoir 9. At the upper end of the part 26 is a reticulated member or screen 27, the meshes of which are formed fine enough so as to impede the flow of the water from the interior of the receptacle 8 through the pipe 26 thereb insurin that a certain amount of water wi 1 always retained within the interior of the receptacle.

The shaft 19 extends through a nipple 28 formed upon one part of the receptacle 8, the said nipple being rovided with an Opening through which e shaft passes. This nipple is screw threaded upon its outer end to engage with a gland nut 29, which gland nut resses packing 30 tightly against the nipp e 28 so as to arm a water tight joint. The end of the shaft is accommodated within a projecting nipple 31 which is likewise recessed to accommodate the shaft, but the. recess in said nipple does not. extend entirely through the same.

The 0 eration of the device is as follows: Gas is ac mitted from the cylinder 1 through the pipe 6, and enters into the interior of the receptacle 8. and likewise water is caused to flow through the pipe 7 to the interior of the receptacle 8, when the engine 5 and pump 2 are started. At such time. the piston rod 12 will reciprocate back and forth, which will cause the gear 16 to be rotated in one direction during the reciprocation of the piston rod in one direct ion and to be rotated in the opposite direction during the reciprocation of the piston 12 in its opposite direction. The motion of the gear 16 will he communi rated to the gear 18 through the shaft 15 and the motion of the gear 18 will be transmitted to the gear 20 and to the shaft ll), which will cause the agitating devim couuccled with the shaft to operate. The a 'itutor will churn and agitate the water wit in the receptacle 8 so that the water will be practically saturated with gas.

The shaft 19 and mixing device may be 0 rated at a rate of speed slower or faster tion the motion imparted to the gear 16, as 7 may be desired, an this is accomplished by substituting for the gears 18 and 20 shown. other gears havin varying numbers of teeth which will give t e rate of rotation to the shaft 19 that ma be desired.

It will be wel understood that the shaft 19 may be driven directly by the reciprocations of the pump piston 12 if such be desired. However, as a rule, the speed of rotation imparted to the mixing device, when no such direct connection is made, is not suflicient to secure the best results in mixing the gas and water, and therefore it is desirable to operate the mixing device at a higher rate of speed. This may be readily accom- 5 plished b the means which I have shown. that is, o emplo ing gears 18 and 20.

I do not con ue myself to the use of a stora e tank in connection with the mixing chamber and a tutor, it being obvious, as before stated, t at the gas and water after passing through the mixing chamber may be used directly m a fountain or may be placed in the customary trans ortation tanks. Furthermore, it is within t e scope of my invention to enlar e the capacity of the mixing chamber so diet the same may retain within its interior any desired quantity of the fluids to be mixcd. Moreover, any desired form of Iiigltating device mag be used.

aving thus descri ed my invention, I claim:

1. In a device of the character described, the combination with a source of gas under pressure, of a pum for supplying water under pressure, sai puma being rovided with a iston rod, of a chambere mixing receptuc e, an agitator within said mixin receptacle, a shaft for operating said a tutor, and a rack and pinion connection tween said pum piston and shaft whereby the agitator wil be operated by the movement of the pump iiston.
